Oxygen regulators for medical gas can generally be divided into the following categories based on their structure and function:
Classified by structural principles.
Piston type oxygen regulator: With a sturdy structure and high reliability, it is suitable for long-term use in hospitals, industries, and high-pressure environments, and is the type with the largest market share.Diaphragm oxygen regulator: With high control accuracy and sensitive response, it is commonly used in critical care, anesthesia machines, and other scenarios that require fine flow control.
Click type oxygen regulator: The flow rate is adjusted through the “click” gear, which is intuitive to operate and convenient for home care and emergency use.
Float type oxygen inhaler: equipped with a float flow meter, commonly used in wards and home oxygen therapy, for oxygen therapy and emergency treatment.
Oxygen regulator with humidification bottle: Integrated humidification bottle, used for long-term oxygen inhalation, humidifies the gas, and improves patient comfort.
Dual head oxygen regulator: simultaneously displays high-pressure cylinder pressure and output pressure/flow rate, commonly used in anesthesia machines, ventilators, and other equipment.
Plug in/Terminal Oxygen Regulator: Installed on oxygen supply terminals or equipment, used for central oxygen supply systems or portable devices.
Intelligent/Digital Oxygen Regulator: Integrated with sensors, display, and communication functions, it can remotely monitor flow and pressure, and is a high-end product.
Classified by function:
Adjustable flow type: The flow can be adjusted continuously or in stages, suitable for different conditions and treatment needs.
Fixed flow type: The output flow is fixed and used for specific treatment scenarios, with simple operation and high safety.
G5/8, G3/4, DIN477 and other threaded interfaces: used for connecting gas cylinders or pipelines in different countries and systems.
Divided by medium:
Pure oxygen regulator: specifically designed for medical oxygen, with an inlet pressure typically reaching 15 MPa (approximately 150 bar) and an outlet pressure of approximately 0.2-0.3 MPa, with a flow range of 1-15 L/min.
Mixed gas regulator: such as helium oxygen mixture (80:20 or 70:30), used for specific treatment or respiratory support.
Classified by security level:
Equipped with safety valve/pressure relief valve: When the outlet pressure exceeds the set value, it will automatically release pressure to ensure safety.
Equipped with a filtering device: a filter is installed at the inlet or inside to prevent impurities from entering the pipeline.
Divided by installation form:
Bottled type: directly installed on oxygen cylinders, used for ward, emergency, and home oxygen therapy.
Panel/Wall Mounted: Fixed on walls or equipment, used for central oxygen supply systems or centralized gas supply stations.
Portable: Small in size, lightweight, easy to carry and move around for use.
Divided by adjustment levels:
Single stage decompression: With a simple structure, it is suitable for scenarios where pressure fluctuations are not significant.
Double stage pressure reduction: It can maintain stable output even when the inlet pressure fluctuates greatly, and is often used for long-distance gas supply or large systems.
